hi all dears

I am using weap-modflow linkage for IWRM simulation in simple area.but runtime of weap-modflow simulation for 72 stress period is very big(2.65 min).how to reduce this runtime? how to force weap to calculate only Some of the results no all the results to reduce runtime? i need to reduce simulation runtime less than 1 min(how to do it?).because i want to evaluate of results by optimization tools (genetic algorithm) in MATLAB.

please help me.I desperately need to do it.
thanks a lot

Hi arash,

What solver does your MODFLOW model run with? Try to use the SIP solver instead of the PCG. This will speed up the MODFLOW model alot. I reduced the runtime of a big MODFLOW model from 28 min to 30sec.

hi cheers,
Thank you for the guide.

I use the SIP solver instead of the PCG. but it dont reduced the runtime.My SIP pakage is illustrated below:

50 5 (MXITER , NPARM)
1 0.01 0 0.01 1 (ACCL HCLOSE IPCALC WSEED IPRSIP)

so Do I need to change one or more parameters in this pakage to reduce the runtime of modflow?

thanks a lot

Arashe aziz,
check this, it may reduce run time:
Edit -> Result variables -> select variables to calculate... with this option you can uncheck the parameters you don't want to be calculated in a specific simulation.
